If you want to add or change a specific DB area, use the adbmodarea command rather than the adbinit command. For details about the adbmodarea command, see 34. adbmodarea (Add and Change DB Areas).

Data DB areas |
The adbinitdbarea operand of the initialization options is used to define the data DB areas that are to be created. |
The DB areas listed above can be created as regular files under the DB directory or as block special files. We recommend that you allocate block special files. You use initialization options of the adbinit command to specify which files are to be created.
